I have a lenovo ideapad u430 with a nvidia GT 730m. I installed ubuntu 13.10 mainly because of the wifi and haswell support, but it just doesn't pick up the nvidia card. On the other hand, ubuntu 12.04 does seem to recognize it in the live cd (usb). So, my questions would be:


is the anything I can do so that my current system recognizes the card?


if not:


can I install ubuntu 12.04 besides my current system? how?


When I click on "install ubuntu" from the 12.04 live cd it tells me that I do not have any other OS in my computer, and gives me the option to delete everything, which would be less than ideal. Gparted also doesn't let me resize my disk (lvm), it says that I only have like 50 mb free.
